When the bean skins float, moin moin has begun
Rub soaked black-eyed peas between your palms in a bowl, and only the thin skins rise to the surface of the water. Scoop up the beans, now pale and white, and you can see that what were dry little seeds a moment ago are already on their way to becoming a steamed batter. From here on, moin moin is a fun dish to make.
Moin moin (also spelled Moi Moi or Moyin-Moyin) is a Nigerian bean dish: skinned beans are ground with chiles and onion, then steamed until set. It looks a bit like a rustic savory custard, but at its core it is all bean. The sweetness of red bell pepper, the aroma of onion and the earthy scent of red palm oil come together in the steam.
First-timers usually get stuck on four things:
- How thoroughly to wash the black-eyed peas for a light texture
- When to add water, and how many milliliters at a time
- What to steam it in if you have no banana leaves
- What to use if you have no red palm oil
The goal is a moin moin that holds its shape without being dry, and that quietly gives way when you slide a spoon in. This version has no add-ins, so you can get a clear sense of the beans and aromatics.
Background: from leaf parcels to small cups
Moin moin is often introduced as a dish of the Yoruba-speaking region. In Nigeria it appears not only at family meals but at parties and weddings as well, eaten alongside jollof rice, fried plantains, pap and more. An article in the Guardian Nigeria also lists several ways to wrap it, including leaves, aluminum foil and dedicated containers.
What's interesting is that there's no single fixed way to wrap it. In a record from Pan-Atlantic University, you can follow in photos as the beans are washed by hand, the skins are floated off, and banana leaves are folded into funnels to receive the batter. The leaves don't just add aroma; they also keep the batter out of the water while it steams.
Meanwhile, an FAO document on cowpea processing describes Moyin-Moyin as a savory steamed black-eyed pea pudding and records making it not only in leaf wrappers but also in empty cans and muffin tins. Using small heatproof cups at home is less a compromise than a practical variation already on record.
The same black-eyed peas become akara (in Japanese) when fried and moin moin when steamed. The steps up to lightening the skinned beans are the same, so one bag of beans can take you to two dishes.
Moin moin goes by several spellings, including Moin Moin, Moi Moi and Moyin-Moyin. How it is wrapped also varies by household and region: in leaves, or steamed in cans or cups.
Not insisting on one "correct" spelling is also a small key to understanding this dish. English-language sources list Moin Moin, Moi Moi and Moyin-Moyin side by side, and both the name and the wrapping vary by region and by household. In a home kitchen you don't need to keep hunting for leaves. Learn the right batter consistency in cups first, then try the aroma of leaves. Done in that order, the difference in equipment becomes part of the dish too.
Ingredients (serves 4)
This makes 6 heatproof cups of about 200 ml each (about 1 liter of batter in total). If you wrap it in banana leaves, use the same amount of batter.
Black-eyed peas are the star of the batter. Switching to chickpeas or red kidney beans changes how the skins come off and how it steams. The first time, it's worth seeking out black-eyed peas so you can appreciate why the skinning step matters. Canned black-eyed peas hold a lot of water and throw off the batter guidelines, so this recipe doesn't use them.
Black-eyed peas are legumes. Anyone who reacts to soybeans, peanuts or other legumes should check the ingredients and any shared equipment. Smoked fish and eggs are optional, but if you use them, only add ones that are already cooked to the batter. On days you use fish, keep separate cups and utensils for fish-free portions. Chiles are potent even in small amounts, so when cooking for a family, leave them out and serve them on the side.
Choosing red palm oil, and substitutes
You only use 20 ml of red palm oil, but its orange color and earthy aroma are what make moin moin taste like moin moin. It also works for Nigerian fried bean dishes and West African stews. If you first want to try just the texture of the beans, you can replace the 20 ml of red palm oil with 20 ml of rice bran oil and it will still steam up well.
Red palm oil and palm nut cream are different products, so when shopping, check the label to make sure it says "red palm oil."
How to make it
Set up the steamer first
Place a steaming rack in a pot at a height where the bottoms of the cups won't touch the water. Use about 3 cm (1 1/4 in) of water below the rack. Choose a pot where the cups stand upright with a little space above them when the lid is on. Keep hot water ready in a kettle so you can top up the pot without interrupting the cooking.
Opening the lid repeatedly while steaming drops the temperature and makes the batter less likely to set. Check the water level only once, after 30 minutes, and gently pour boiling water in below the rack.
Four cues for the finished texture
Skins: rinse off what floats rather than chasing every one
It's still edible if a few skins remain, but too many make the batter gritty on the tongue. Wash until at least 80 percent of the beans look white, and that's plenty for homemade moin moin. Rather than forcing yourself to pick off skins one by one, be thorough about pouring off the skins floating on the surface.
Don't add the water all at once
How much water you need depends on how much the beans absorb and how juicy the pepper is. Start blending with 150 ml, then add the rest 10 ml at a time. If the finished batter runs off a spoon like a thin liquid, there's too much water; if it falls in a lump that won't flow, there's too little. A thick ribbon that holds its trail for 2 seconds is the easiest consistency to steam.
Judge the air by the whisk marks
English-language recipes also describe whisking the batter before steaming to lighten it. Tiger Foods' method for ekuru shows the black-eyed peas being skinned and then whisked to lighten the batter. For moin moin, it's easier to work with when you whisk until fine bubbles are spread throughout, rather than whipping up big bubbles.
Stronger steam isn't better
If the boil is too vigorous, the cups rattle and drips from the lid are more likely to get into the batter. Keep it on medium heat, with a thin stream of steam escaping from the edge of the pot and the water moving gently. Running dry leads to both scorching and undercooking, so check the water level at least once during the 45 minutes.
Variations: white ekuru and moin moin with fillings
Start with egg or smoked fish on the side
The records from the Guardian Nigeria, FAO and Pan-Atlantic University all mention variations with egg, fish, shrimp and the like. Make it plain the first time, then add hard-boiled egg or smoked fish on the side once you've seen how it steams; that makes it easier to judge the batter's moisture and flavor. If you do add fillings, place a small amount of cooked filling in the center. Keeping the cups from getting too large helps everything cook through evenly.
Make it like white ekuru
Leave out the red bell pepper and red palm oil, steam the batter with just salt and onion, and serve it with a hot sauce, and you move toward ekuru, introduced as the white moin moin of southwestern Nigeria. Tiger Foods describes ekuru as "white Moin Moin" and pairs it with spicy ata din din. It is another face of the same batter, not a substitute for the red moin moin in this recipe.
When you have no banana leaves
Heatproof cups give less leafy aroma, but they make the moisture easier to manage and are well suited to judging success on your first try. The FAO document also records methods using muffin tins and empty cans. If you use cans, use only ones with a food-grade lining that are free of scratches and rust. If you're unsure, heatproof cups are the safer choice.
Tools for a smooth bean batter
This dish needs a thick paste, not liquefied beans. A blender will work, but the most common mistake is adding too much water when it won't turn. A food processor can keep a thick batter turning without extra water. When using a blender, process small amounts at a time, and if it stalls, reduce the load rather than adding water.
With the amounts in this recipe, don't pack it all in at once; working in 2 batches keeps the blade turning more easily and makes the batter's moisture easier to read.
Fixing problems, and storage
| Problem | Likely cause | Fix |
|---|---|---|
| Center is liquid | Cups too large, water not boiling vigorously enough, not steamed long enough | Replace the lid and steam over medium heat in 5-minute increments |
| Firm outside, heavy inside | Batter too thick, not enough air | Next time, add 10 ml more water and whisk 2 minutes longer |
| Watery surface | Drips from the lid, steam too strong | Wrap the lid in a towel and bring the water back to a gentle simmer |
| Gritty bits of bean | Skins left on, not blended enough | Next time, rinse off the skins once more and blend in small batches for longer |
| Red palm oil too strong | Too much oil, or you're not used to the aroma | Next time, cut it to 10 ml and replace the rest with rice bran oil |
Once the steamed moin moin has cooled a little, wrap each one individually, refrigerate and eat within about 2 days. To freeze, unmold them, wrap each one individually and use within about 2 weeks. To serve, reheat in a steamer for 8–10 minutes and eat the same day once they're hot all the way to the center. Avoid refreezing and leaving them at room temperature for long periods.
FAQ and sources
Which black-eyed peas should I buy?
Choose dried black-eyed peas. If you can find pre-skinned beans, the work goes faster, but absorption varies by product, so start with less water and adjust. Substituting red kidney beans or chickpeas changes the texture, even though it's still a steamed bean dish.
Are banana leaves essential?
No. Leaves bring aroma and are easy to wrap with, while heatproof cups make it easier to judge moisture and doneness. Steam in cups the first time, then try leaves, and you can compare how the wrapping changes things.
Can I make it without heat?
Yes. Leave out the chile and keep the sweetness of the red bell pepper and the aroma of the onion. Anyone who wants heat can add sauce at the table. That's easier for the whole family than putting a lot into the batter from the start.
What should I watch out for when using a blender?
Don't add a lot of water at once just because the beans won't turn. Blend small amounts at a time, stopping to scrape down the sides. If you add too much water and it turns liquid, add a small amount more skinned black-eyed peas to bring the consistency back. Only add beans that have been fully soaked in advance.
What can I do with leftover black-eyed peas or aromatics?
Move on to akara (in Japanese), where black-eyed peas are fried, and you'll use the skinning and aerating steps again. For a rice dish, pair it with jollof rice; for a bean stew, Ghana's red red (in Japanese). Even within West Africa, each takes a different role at the table.

Moin moin may look like nothing more than steamed beans, but the sequence of skins, water, air and steam translates directly into its texture. If you love the aroma of red palm oil, carry it on to your next West African dish. If you just want to learn the texture first, it's fine to make it with rice bran oil. Once you've learned the sound of skins washing away and the steam rising from the lid, try adding leaves or fillings one at a time.
